DETAILED DESCRIPTION

Some embodiments of the disclosure provide a Cloud Detection System that receives sensor data from mobile equipment and/or vehicles. The Cloud Detection system monitors and processes the received sensor data to detect events such as collisions or accidents between the vehicles. The event is thus detected and recorded remotely at the Cloud Detection System.

In some embodiments, sensor data from two or more mobile devices equipped with GPS (global positioning system), accelerometer and video sensors are stored in a Cloud Data Center. A processing algorithm identifies a collision between the vehicles by analyzing the spatial information and temporal information that have been uploaded to the cloud datacenter, particularly position and motion information that indicates the two vehicles were at the same place at the same time.

Once the collision event is detected, some embodiments attach additional information to the event, information such as video recording, air bag deployment record, braking record, and speed record that are recorded by the mobile equipment/vehicles involved. In some embodiments, video sensors run in continuous loops and can provide pre-event recording and/or information leading up to the collision. In some embodiments, data from biometric sensors attached to the operators of the mobile equipment/vehicle are also included in the event. In some embodiments, stationary sensors situated in the vicinity of the collision are also monitored to provide additional information on the event.

FIG. 1 illustrates a Cloud Detection System 100 that monitors sensor data from mobile equipment/vehicles in order to detect events such as collisions between two or more vehicles. The system comprises a cloud datacenter 110 that receives sensor data from vehicles 121-129. By analyzing the received sensor data from the vehicles, the cloud datacenter 110 identifies an event and generates a report 190 about the identified event. In the illustrated example, the vehicle 121 and the vehicle 122 have collided at a particular location and a particular time. The cloud detection system 100 uses the sensor data uploaded by the two vehicles 121 and 122 to detect the collision event.

The vehicles 121-129 are mobile units that can move about from one place to another, and can travel to different places at different times. Such a mobile unit can be an automobile, a motorcycle, a pedestrian, or any other moving object or apparatus. In some embodiments, each mobile unit includes or carries equipment or devices that allow the mobile unit or vehicle to become part of the cloud detection system. In some embodiments, the vehicle equipment can include sensors that are physically attached to the vehicle. The vehicle's equipment can also include sensors that are provided by one or more independent mobile devices (such as a smart phone) that are carried aboard the vehicle by its operator/driver (or in the pocket of a pedestrian).

The vehicle's equipment includes sensors for capturing position and motion information regarding the vehicle. The position information is data for identifying the location/position of the vehicle at different moments in time. The motion information is data for describing the motion of the vehicle at different moments in time. As illustrated in FIG. 1, the vehicle 121 includes sensors such as GPS, accelerometer, speedometer, airbag, video recorder, brake, etc. Some embodiments also include sensors that are not illustrated, such as video sensors, tire pressure sensors, etc. In some embodiments, devices physically attached to the vehicle provide some of the sensors, such as GPS, airbag, brake, accelerometer, etc. In some embodiments, independent devices carried aboard the vehicle provide some of the sensors such as GPS, speedometer, and accelerometer. In some embodiments, different vehicles have different types of sensors, and some types of sensors are present in some vehicle but not in others.

In some embodiments, the GPS provides GPS coordinates that can be used to derive position information and/or motion information. In some embodiments, sensors such as video recorder also provide position information that can be used to identify the location of the vehicle. In some embodiments, output from sensors such as accelerometer, speedometer, video recorder, brake sensor, tire pressure is used as motion information of the vehicle. In some embodiments, records of emergency equipment deployment such as airbag deployment are considered as motion information because they are indicative of sudden change in motion (sudden acceleration or deceleration) of the vehicle.

In some embodiments, the vehicle's equipment includes time-stamping mechanisms so each recorded set of position and/or motion information produced by the sensors would be associated with a timestamp. In some embodiments, the vehicle's equipment also includes vehicle identification reporting mechanism so the cloud datacenter would be able to associate the uploaded sensor data with the identity of the vehicle uploading the data.

The vehicle's equipment also includes communications device for communicating with the cloud datacenter 110 such as wireless transceivers in some embodiments. Each vehicle's communications capability allows the vehicle to upload its captured motion and position data to the cloud datacenter 110 through one or more communications mediums. In some embodiments, such communications are conducted wirelessly through wireless communications medium such as WiFi or wireless phone networks. In some embodiments, the data so wirelessly communicated are relayed to the cloud datacenter 110 through networks of wired and/or wireless communications mediums such as Ethernet cables, CATV cables, or fiber optics cables. In some embodiments, some of the communications mediums linking the vehicles 121-129 and the cloud datacenter 110 rely on the Internet, and the motion and position information communicated to the cloud datacenter is conducted through Internet traffic. In some embodiments, each vehicle's communications capability also allows the vehicle to download or receive various data or report, such as those regarding other vehicles or conditions on the road and display them to the operator of the vehicle.

The cloud datacenter 110 is a system that monitors the vehicles 121-129, detects events such as collisions or encounters with road surface defects, and generates reports of the detected events. It receives the upload of the position and motion information from the vehicles 121-129 and analyzes the received information to detect events such as collisions or potential collisions. In some embodiments, the cloud datacenter 110 also receives upload of information from stationary sensors 130 that are not attached to or aboard the vehicles.

In some embodiments, the cloud datacenter 110 is a computing device or a collection of computing devices that are capable of receiving upload data from the vehicles through the Internet or other communications mediums. In some embodiments, such computing device(s) are situated at a data center or an Internet service provider. In some embodiments, such computing devices are provided or maintained by a provider of Internet content (e.g., a traffic information server). In some embodiments, the cloud datacenter is a collection of devices that are situated at different physical locations interconnected by the Internet or the computing cloud to perform the operations of the cloud datacenter.

As illustrated, the cloud datacenter 110 receives uploads of position and motion information (or sensor data) from the vehicles 121-129 (and stationary sensors 130) and stores the uploaded information at a vehicle data storage 140. As illustrated, the storage 140 includes sets of uploaded motion and position information from the different vehicles. Each set of motion and position information is associated with a vehicle identifier for identifying the vehicle that uploaded the set of information. Each set of motion and position information is also associated with a time stamp for identifying the point in time at which the vehicle is having the position and motion described by the set of position and motion information.

Based on the uploaded position and motion information in the storage 140, the cloud datacenter 110 performs event detection (illustrated as an event detector module 150) and event reporting (illustrated as an event reporter module 160) based on the uploaded data at the storage 140. Each detected event causes the cloud datacenter to generate a report such as the report 190, which describes the detected event. Such description in some embodiments include time and location of the event, identities of the vehicles involved in the event, and other information such as video or photographs of the event (which may be uploaded from the vehicles). The content of the report is then provided to subscribers (such as the vehicles 121-129) to provide traffic information, warnings of road hazard, and other types of notifications.

In some embodiments, the event detector 150 of the cloud datacenter 110 identifies events by monitoring and analyzing the uploaded position and motion information, specifically by correlating uploaded position and motion information of one vehicle with other vehicles. In some embodiments, the cloud datacenter receives position and motion information from the vehicles and identifies an incident involving two of the vehicles by correlating the motion and position information of one vehicle with the motion and position information of another vehicle. The cloud datacenter 110 then reports the identified incident to e.g., subscribers, emergency services, etc.

For some embodiments, FIG. 2 conceptually illustrates the detection of a collision event by examining the position and motion data uploaded by the vehicles. As illustrated, the vehicle data storage 140 of the cloud datacenter 100 stores position and motion information for vehicles 121-129. Specifically, FIG. 2 shows portions of the position and motion information for vehicles 121, 122 and 123 (illustrated as position and motion histories 221, 222, and 223; position and motion information of vehicles 124-129 are not illustrated for simplicity). For each vehicle, the position and motion information (including GPS position, speed, acceleration, airbag deployment, etc.) at various time instants are recorded. The event detector 150 of the cloud datacenter 110 in turn uses the position and motion information of the vehicles to detect collision events.

As illustrated, the position/motion history 221 shows that the vehicle 121 at time 12:01:00 is at position “N40.1 W74.3” having speed of 0 mph with airbag deployed (at entry 201). The position/motion history 222 shows that the vehicle 122 at time 12:02:00 is also at position “N40.1 W74.3” having speed of 0 mph with airbag deployed (at entry 203). The event detector 150 in some embodiments therefore correlates the position/motion histories 221 and 222 and determined that a collision event has occurred between these two vehicles (121 and 122) at position “N40.1 W74.3” and at time 12:02:00.

Different embodiments use different techniques to detect collision events based on the uploaded position and motion data. Some embodiments compute a collision metric for each vehicle based on the received position and motion information. In some embodiments, the collision metric of a vehicle is based on a heading, speed, and acceleration data of a vehicle that are gleaned or computed from information uploaded by the vehicle. The collision metric of some embodiments is also based on emergency equipment deployment record, such as that of an airbag. In some of these embodiments, the cloud datacenter identifies or detects a collision incident by identifying a location and a time at which two or more vehicles having collision metrics exceeding a threshold. Some embodiments compute the collision metric of a vehicle based on its spatial and temporal relationship with other vehicles, such as the vehicle's speed and position relative to other vehicles (that are derived from the uploaded position and motion information). Some of these embodiments compute the collision metric as a probability of collision based on the relative speed and position, where the cloud datacenter detects collision by examining whether the collision metric has exceeded a threshold probability of collision.

In the example of FIG. 2, the event detector 150 is computing collision metrics for vehicles 121-123 (and others not illustrated), which are used to detect collision events. For example, as mentioned, airbag deployment record is used as “motion information” for computing the collision metric of a vehicle in some embodiments. In some embodiments the deployment of an airbag is weighed heavily in the computation of collision metric. Since both vehicle 1 and vehicle 2 have their airbags deployed at the same place and at the same time according to entries 201 and 203 (at time 12:02:00 and position “N40.1 W74.3”), their collision metrics would exceed a detection threshold at the same place and time. The event detector 150 therefore determines that a collision event has occurred between those two vehicles. Some embodiments define at the same place and time as being “close enough,” i.e., having spatial and temporal differences that are within a threshold.

As mentioned, not all vehicles in the cloud detection system are equipped with the same set of sensors, and some vehicles may not be equipped to report the deployment of airbags or other emergency equipment. Some embodiments therefore rely on relative distance and speed between the vehicles to detect a collision event. In some of these embodiments, the event detector computes collision metrics for each vehicle based on the vehicle's relative speed and position with other vehicles. In the example of FIG. 2, the event detector 150 computes collision metrics of vehicle 1 based on its relative distance and speed with vehicle 2 and other vehicles and determines that at time 12:02:00, the collision metrics of both vehicles has exceeded a threshold and that a collision has likely occurred. For example, according to history 221 and 222, the relative distance of the vehicles is extremely close (e.g., within a threshold distance) around the time 12:01:00, while both vehicles are experiencing significant deceleration (vehicle 1 reporting significant westward acceleration while heading eastward and vehicle 2 reporting significant eastward acceleration while heading westward). The relative close distance between the two vehicles based on the uploaded position data and the sudden acceleration in the opposite direction based on the uploaded motion data results in a collision metric for both vehicles 1 and 2 to rise near or above the collision detection threshold value.

In some embodiments, other sensor readings that are uploaded to the cloud datacenter are also factored into the computation of collision metric, such as airbag deployment, tire pressure, video record, etc. For example, it is possible that the received speed/position/acceleration data failed to capture a particular collision event, but the existence of other sensor data or motion information would nevertheless cause the collision metric to exceed the threshold value and allow detection of the accident (e.g., airbag deployment, sudden change of tire pressure of two vehicles near the same place and time, etc.) In some embodiments, the event detector also uses information uploaded by other sources to confirm an accident, sources such as other vehicles or stationary sources in the vicinity of the event.

Upon the event detector 150 having determined that a collision has occurred based on the computed collision metrics, the event detector 150 produces a collision event report 290. As illustrated, the collision event report 290 identifies the vehicles that are involved in the accident (vehicles 1 and 2) as well as the time and place of the accident (at time 12:02:00 and position “N40.1 W74.3”). In some embodiments, such report or the information regarding the detected collision is provided to other vehicles and/or other agencies. In some embodiments, a collision report also includes video recordings prior to the event. Some embodiments receive such video recording from the vehicles involved in the accident, or other vehicles or stationary sources that are near the scene of the accident. Some embodiments identify other vehicles and stationary sources near the scene of the collision based on the position information recorded in the vehicle data storage 140. In some embodiments, such recordings include a recording of an interval of time before and after the detected collision event.

Some embodiments use the information in the collision report (e.g., 290) to notify relevant services and agencies. In some embodiments, such notification is based on a location of the detected collision event and/or the identity of the vehicles involved in the collision that is embedded in the collision report. FIG. 3 illustrates the notification of services and agencies based on a detected collision event.

As illustrated, the generated report 290 for the identified collision is forwarded to the event reporter 160 of the cloud datacenter 110. The event reporter 160 in turn notifies various service agencies 320 such as emergency services, insurance agencies, towing services, and substitute transportations (such as rental car, taxi, etc.) Some of these services are identified based on the location of the identified collision event, such as emergency services, towing services, auto repair shops, or taxi services. Some of these services are identified based on the identities of the vehicles involved in the collision, such as insurance agencies and rental car companies.

Some of these services are identified based on the intended destination of the vehicle. The intended destination of the vehicle is available to the cloud datacenter if the vehicle involved in the collision was running a navigation application and have uploaded the intended destination to the cloud datacenter. The intended destination can also be based on the work address or home address of the user of the vehicle. The cloud datacenter 110 may select a provider of the substitute transportation based on the intended destination and relay the intended destination information to the provider of the substitute transportation.

In some embodiments, the event detector 150 provides an estimate of the severity of the detected collision in the report. The cloud datacenter 110 uses the estimated severity to determine what types of agencies and services to contact. For example, the cloud datacenter 110 can determine whether to call an ambulance or the police based on the identified severity.

In some embodiments, the cloud datacenter 110 includes a post-event logistics database 310, which indexes service agencies according to vehicle identities and/or locations and/or intended destination and/or severity of the accident. The cloud datacenter 110 uses the logistical information stored in the post-event logistics database 310 to look up the service agencies that it should contact or deploy for the identified accident. In some embodiments, the cloud datacenter 110 receives logistical information from individual vehicles and then populates the post-event logistics database accordingly. Insurance companies may also populate the logistical database 310 with logistical information for the vehicles that they insure.

The cloud data center 110 uses the content of the post-event logistics database to deploy services for individuals involved in the accident. For example, the cloud center 110 may contact a ride service to take the persons involved in the accident to the nearest user preferred car rental company, or contact a towing service to tow the damaged vehicle to a user preferred auto repair shop. The user preferences are provided by the post-event logistics database.

The cloud center may also contact tow-truck to tow the vehicles to the nearest user-preferred auto-shop. Such user preferences are available to the cloud data center as part of the post-event logistics database 310. The cloud data center may also forward a report to the all parties of the collision (or at least those that are participant of the cloud detection system 100). Such report in some embodiments include information about the accident itself (location, time), the identity of vehicles involved, as well as other information such as insurance information that are provided by the post-event logistics database 310.

In some embodiments, in addition to detecting events such as collisions based on uploaded position and motion information, the cloud detection system also provides warnings to subscribers based on analysis of the position and motion information. In some embodiments, the cloud detection system uses the uploaded motion and position data to identify a hazard vehicle as well as vehicles that are endangered by the identified hazard vehicle. The system then issues warnings to the identified endangered vehicles regarding the hazardous vehicle. In addition to issuing warnings to the identified endangered vehicles, the cloud detection system can also make information regarding the identified hazard vehicles available to interested parties such as law enforcement agencies or insurance companies (e.g., the insurance companies associated with the identified hazard vehicles.)

In some embodiments, the cloud datacenter identifies hazardous vehicles by computing a hazard metric for each of the plurality of vehicles based on the received position and motion information. A vehicle having a hazard metric that is above a threshold is identified as a hazard vehicle. In some embodiments, the hazard metric of a vehicle is computed based on a speed of the vehicle and a condition of the road that the vehicle is traveling on. In some embodiments, the hazard metric of a vehicle is computed based on a history of the motion information of the vehicle over an interval of time.

FIG. 4 conceptually illustrates the cloud detection system detecting hazard vehicles and issuing warnings to endangered vehicles. FIG. 4 illustrates vehicles on two different roads. Vehicles 121-123 (labeled as vehicles 1, 2, and 3) are traveling in road 401 and vehicles 124-128 (labeled as vehicles 4, 5, 6, 7, and 8) are traveling on road 402. At least some of the vehicles illustrated are configured to upload position and motion information to the cloud datacenter 110, accordingly. The cloud datacenter 110 has already detected that vehicles 121 and 122 are involved in a collision by analyzing the uploaded data.

Based on the uploaded data, the cloud datacenter 110 has also determined that one of the vehicles (vehicle 125) traveling on the road 402 is a hazard to other vehicles (e.g., for being too fast or engaging in other dangerous driving behaviors). The cloud datacenter identifies the vehicle 125 as being a hazard vehicle based on the motion and position data uploaded by the vehicle 125. The cloud datacenter can also identify the vehicle as being a hazard vehicle based on motion and position data uploaded by other vehicles such as the vehicle 128, which had recorded unsafe relative distance and speed with respect to the vehicle 125.

The cloud datacenter 110 identifies vehicles 124, 126, and 127 as vehicles that are endangered by the hazard vehicle, again according to the uploaded position and motion data. The cloud datacenter therefore issues warnings to vehicles 124, 126, and 127 about the hazard posed by vehicle 125. Since vehicles 121-123 are traveling on a different road (401), they are not identified as being endangered, so the cloud datacenter does not issue warnings about the vehicle 125 to those vehicles (i.e., 121-123). In addition to issuing warnings to the endangered vehicles, the cloud datacenter also reports information regarding hazard vehicle 125 to insurance agencies and/or law enforcement agencies (among service agencies 320).

In some embodiments, endangered vehicles are identified by identifying vehicles that are positioned within a threshold distance of the hazardous vehicle, the threshold distance being determined by (i.e., a function of) the speed of the hazardous vehicle and the condition of the road that the vehicles are traveling on. Some embodiments identify endangered vehicles by computing a projected path of the hazardous vehicle and identifying vehicles that are likely to be in the projected path of the hazardous vehicle.

In the example illustrated by FIG. 4, the cloud datacenter 110 computes hazard metrics for vehicles 121-127 from the data stored in the vehicle data storage 140. Based on the computed hazard metrics, the cloud datacenter 110 has determined that the vehicle 215 is a hazard vehicle because its hazard metric has exceeded threshold. This hazard metric can be computed based on the speed (e.g., 90 mph) and the condition of the road 402. The hazard metric can also be computed based on other factors, such as the vehicle's history of acceleration (e.g., erratic acceleration pattern) or even the driver's prior record. In some embodiments, the hazard metric is computed based on speed, distance traveled, average distance maintained between vehicles. The computation of hazard metric may also rely on recordings from video cameras on board vehicles or proximity sensors. These metrics could be recorded by the on-board electronic in each vehicle or through other new sensors and communicated to the cloud datacenter 110.

The cloud datacenter 110 computes hazard metric for detecting several different types unsafe driving behaviors, such as tail-gaiting (e.g., following another vehicle too closely for too long period of time), cutting-off (e.g., abrupt lane change right in front of other vehicles), and intentional obstruction of other vehicles (e.g., speeding when someone is trying to pass, abrupt acceleration or slowing down so that no one can pass, etc.). To detect these unsafe driving behaviors, the cloud datacenter 110 may for example, use video recording or proximity sensor data of other vehicles (e.g., the vehicle 128) to determine if a vehicle has executed a dangerous maneuver that is too fast or abrupt based on its relative speed and distance from other vehicles. For example, to detect tail gating, the datacenter uses the uploaded the motion and position information from the vehicles to determine whether any vehicle is closer than a threshold distance at a speed over a threshold speed to another vehicle for over a threshold period of time.

With the vehicle 125 identified as being a hazard vehicle, the cloud datacenter 110 identifies vehicles that are endangered by the vehicles 125, namely vehicles 124, 126, and 127 in the example of FIG. 4. The cloud datacenter 110 identify these vehicles as being endangered because of their proximity to the vehicle 125 (e.g., within a distance that is too close considering the speed of the hazard vehicle). The cloud datacenter 110 identify these vehicles as being endangered because they are computed as being in the likely path of the hazard vehicle. In this case, the cloud datacenter 110 recognizes from the uploaded data that the vehicles 124, 126 and 127 are in the same road as the hazard vehicle 125 and, therefore, endangered. The cloud datacenter 110 also recognizes that the endangered vehicles 124, 126 and 127 are to the east of the hazard vehicle 125, which is its direction of travel.

FIG. 5 conceptually illustrates two processes 501 and 502 performed by the cloud detection system, specifically at the cloud datacenter 110. The process 501 is for detecting and reporting collision event, while the process 502 is for identifying hazard vehicles and issuing warnings to endangered vehicles. In some embodiments, the cloud datacenter operates both processes 501 and 502 at the same time. In some embodiments, the cloud datacenter has several processing units or computing devices that simultaneously execute several instances of the processes 501 and 502.

The process 501 starts by examining (at 510) position and motion information collected from different vehicles to identify two or more vehicles that are near the same place at about the same time. The process computes (at 520) a metric for the probability of collision event/accident between the two or more identified vehicles based on the position and motion data received from those vehicles. In some embodiments, the process computes the collision metric based the relative speed and position of the vehicles (computed from position, speed, heading, and acceleration of the vehicles). The process may also compute the collision metric based on other upload information such as airbag deployment record, brake sensor, tire pressure, etc.

The process 501 determines (at 525) whether the computed collision metric exceed threshold. If so, a collision event has been detected and the process proceeds to 530. If the computed collision metric does not exceed threshold, the process 501 ends. The detection of collision event is described by reference to FIG. 2 above.

At 530, the process receives pre-event video or other available information related to the detected collision event from the vehicles involved in the identified event. The process also uses (at 535) the location of the detected collision event to identify other vehicles or stationary sources that are near the scene of the accident. The process retrieves (at 540) relevant recording or sensor information from these other identified sources.

The process reports (at 545) the site of the accident as a hazard to vehicles that are participant or subscribers of the cloud detection system. The process also notifies (at 550) relevant services and agencies based on the identity of the vehicles involved in the collision event and based on the location of the event. The identification and notification of service agencies upon a detection of a collision is described above by reference to FIG. 3. The process 501 then ends.

The process 502 starts by examining (at 560) position and motion data collected from different vehicles to identify a vehicle (the hazard vehicle) that poses a hazard to other vehicles on the road by computing a hazard metric for each vehicle. Once a vehicle has been identified as a hazard vehicle, the process identifies (at 570) other vehicles that are endangered by the hazard vehicle based on the uploaded position and motion data. The process issues (at 580) a warning to each of the identified endangered vehicles. The process also reports (at 590) information regarding the hazard vehicle to agencies such as law enforcement or insurance agencies. The identification of hazard vehicles and issuance of warning regarding hazard vehicles are described by reference to FIG. 4 above. The process 502 then ends.

It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed. Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider. Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.

Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations. Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).

A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.

Referring now to FIG. 7, illustrative cloud computing environment 750 is depicted. As shown, cloud computing environment 750 includes one or more cloud computing nodes 710 with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone 754A, desktop computer 754B, laptop computer 754C, and/or automobile computer system 754N may communicate. Nodes 710 may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment 750 to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices 754A-N shown in FIG. 7 are intended to be illustrative only and that computing nodes 710 and cloud computing environment 750 can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser).
